MATLAB: Is the space between items in the Pop-up menu different depending on the size of the GUI

guiguidelinuxmacMATLABmenupop-uppopupresizespaceunix

This behavior seems to occur on UNIX, Linux, and Mac, but not on Windows.

Best Answer

The Xwindow server determines the space between items in a pop-up menu. The only way to make sure that the space between items in a pop-up menu does not change is to prevent the GUI from being resized. This can be accomplished by setting the GUI Option Resize Behavior to Non-resizeable. (The GUI Options dialog box is available from the Tools menu in GUIDE.)

In your radio button (actually the button group since you must have 4 exclusive radio buttons) SelectionChangeFcn callback function:

Tag=get(hObject,'Tag')
switch Tag
case 'radiobutton1'
      ctqString= {'Option0'; 'Option1'; 'Option 2'; 'Option3'};
case 'radiobutton2'
      ctqString= {'Option10'; 'Option11'; 'Option 12'};
end
set(handles.ctqMenu,'String',ctqString);

MATLAB: How to change the overall height of a pop-up menu UICONTROL

The height of a pop-up menu is automatically determined by the size of the font, except for on a Mac, in which case the height cannot be modified. The value you specify for the height in the 'Position' property has no effect.

In general, pop-up menus are used to open and display a list of choices when pressed; when not open, a pop-up menu indicates only the current choice. Because of this designed behavior, manually increasing the height of a pop-up menu to display multiple options is not available and a listbox UICONTROL may be a better option to display both the selected and nonselected choices.
